## Section 10.4

Arcs and Chords

### Theorem 10.5

• In the same circle, or in congruent circles, two minor arcs are congruent if and only if their corresponding chords are congruent.

### Perpendicular Diameter Theorem(10.6)

• If a diameter of a circle is perpendicular to a chord, then the diameter bisects the chord and its arc.

### Thm 10.7

• If one chord is a perpendicular bisector of another chord, then the first chord is a diameter.

### Congruent Chords Theorem (10.8)

• In the same circle, or in congruent circles, two chords are congruent if and only if they are equidistant from the center.
